If you’re sick of email bounces, wasted credits, or just want more control over how your lists are cleaned, you’re in the right place. This guide is for anyone using Verifybee who wants to move beyond “set it and forget it” and actually tweak the verification process to fit their own needs—whether that’s to catch more bad emails, avoid false positives, or just stop burning through your credits.
Most people just upload their list and hope for the best. But Verifybee gives you more control if you know where to look. Here’s how to make the platform work for you, not the other way around.
Why Bother Customizing Verification Rules and Filters?
Before you jump in: default settings are fine for quick jobs, but they’re generic. If you’re managing a big campaign, have specific bounce pain, or need to get picky about what’s “valid,” you’ll want to dial things in.
Custom rules and filters let you: - Avoid false positives that cost you good leads - Ignore “catch-all” or disposable domains if you want - Tweak sensitivity so you’re not too strict or too loose - Save money by not verifying addresses you don’t even care about - Actually trust your cleaned list
If you’re sending to a niche audience, or your boss is on your case about deliverability, these settings matter.
Step 1: Know What You Can Actually Customize
Verifybee’s customization lives in two main places: - Verification rules: Decide which emails are considered “valid” or “invalid” (e.g., catch-alls, role accounts, disposable emails). - Filters: Decide what gets included or excluded from your exported/cleaned list.
You’ll find these options when you upload a list, or you can set account-wide defaults under your settings.
Honest take: Some options are more useful than others. Don’t stress about every checkbox—focus on what moves the needle for your use case.
Step 2: Accessing Rules and Filters in Verifybee
Here’s how to actually find these settings:
- Log in to Verifybee and head to your dashboard.
- Upload a new list (or pick an existing one you want to re-verify).
- Before starting the verification, look for a section labeled something like “Advanced Settings,” “Rules,” or “Filters.”
- Sometimes these are hidden behind a little gear or “more options” button. Click around if you don’t see them off the bat.
- For account-wide defaults, click your profile icon > Settings > Verification Preferences.
Pro tip: Start with list-specific settings until you know what you like. Don’t change your global defaults until you’re confident.
Step 3: Customizing Verification Rules
Here’s where things get granular. The main rules you can tweak usually include:
3.1 Catch-All Domains
What it is: Domains that accept any email (even made-up ones), making it tough to know if your email will actually hit a real inbox.
- Default: Some platforms flag these as “risky” or “unknown.”
- Should you filter them? Depends.
- If you care about only guaranteed inboxes, exclude them.
- If you’re in B2B and a lot of legit companies use catch-alls, you might want to keep them.
What works: Test a small batch. If your bounce rate is low, don’t be too strict.
3.2 Role Addresses
What it is: Emails like info@, sales@, admin@. Rarely tied to a real person.
- Default: Usually flagged as “role accounts.”
- Should you filter them?
- For newsletters and promotions, probably yes (they rarely reply).
- For business outreach or support, maybe not.
What doesn’t work: Sending personalized emails to these—they’re almost always ignored.
3.3 Disposable/Temporary Emails
What it is: One-time-use emails from services like Mailinator or Guerrilla Mail.
- Default: Filtered out by most verification tools.
- Should you filter them? Yes, unless you have a very specific reason not to.
What to ignore: If you’re running a freebie or contest, and just want numbers, you might let these through—but don’t expect engagement.
3.4 Syntax and Format Checks
- What it is: Basic “does this look like an email?” test.
- Should you filter them? Always. No one’s at john..doe@@gmail, ever.
3.5 Free Email Providers (Gmail, Yahoo, etc.)
- Should you filter them?
- For B2C, keep them.
- For B2B prospecting, you may want to filter out non-corporate addresses.
Caution: Don’t get too clever—people use Gmail for business all the time.
Step 4: Setting Up Filters for Export and Actions
Filters let you say, “Only give me the emails that pass my rules,” or “Separate out the risky ones so I can handle them differently.”
4.1 Include or Exclude by Status
Most platforms (Verifybee included) label emails as: - Valid - Invalid - Risky (catch-alls, unknown, etc.) - Disposable - Role
How to use: - Export only “valid” emails for a “safe” send. - Export “riskies” to a separate list for manual review (if you want to be thorough).
4.2 Custom Tags and Segments
Some power users like to tag or segment emails by type (e.g., all catch-alls, all role addresses). This is handy if you want to try different campaigns or follow-up tactics.
Pro tip: Don’t over-segment unless you actually have a plan for each group. Otherwise, you’ll just drown in CSVs.
4.3 Automate Filters for Future Lists
In Verifybee, you can usually save your favorite filter settings as a template or default, so you don’t have to re-click everything next time.
What works: Set it once, forget it until your needs change.
Step 5: Save, Test, and Iterate
Don’t trust any tool 100%—Verifybee is good, but no verification service is perfect. Here’s how you stay sane:
- Save your custom rules and filters so you don’t have to start from scratch each time.
- Test with a small sample before running your entire list. See what gets filtered out, and check if you agree.
- Send a small campaign to your “valid” list. Watch your bounce and engagement rates. If things look off, tweak your rules.
- Keep a backup of your raw data, just in case you need to re-run with different settings.
What to ignore: Don’t obsess over every possible filter. Focus on your real goals: fewer bounces, more replies, and not wasting money.
Pro Tips and Common Mistakes
- Don’t get too strict: If you filter out every “risky” or “unknown,” you might lose good leads—especially in B2B.
- Don’t get too loose: Leaving in disposables and invalids will kill your sender reputation fast.
- Check your export: Sometimes “filtered” lists still include stuff you didn’t want. Always double-check.
- Verify in batches: If you’re new, run smaller lists and learn as you go.
- Ignore the hype: No tool (including Verifybee) can guarantee 0% bounces. Be realistic.
Wrapping Up: Keep It Simple
Customizing your verification rules and filters in Verifybee isn’t rocket science, but it is worth a little upfront effort. Start simple. Focus on the filters that actually matter for your goals. Test, tweak, and don’t be afraid to adjust as you learn what works for your audience.
Don’t chase perfection. Just aim for fewer bounces, more real contacts, and not wasting your money. That’s what really counts.
